Question

. A can do a piece of work in 12 days, while B can do it in 10 days. In how (3)

days will they finish the same work both working together?​

Answer 1

Answer:

if a does a piece of work in 12 days

then, the work done by a in 1 day will be = 1/12

and the work done by b in 1 day will be = 1/10

So, 1/12 + 1/10 = 5+6/60 = 11/60
